The outcomes of component separation technique versus no component separation technique in the repair of large ventral hernias and impact on quality of life: a multicenter retrospective cohort study.

PURPOSE

This study aimed to compare the results of patients who underwent anterior component separation techniques (ACST) and those who did not undergo component separation techniques (non-CST) in complicated ventral hernia repairs (VHRs) and to investigate the effect of these techniques on quality of life (QoL).

METHODS

A total of 105 patients who were operated for large ventral hernias were retrospectively analyzed. The patients were divided into the ACST group (n = 48) and the non-CST group (n = 57). Demographic, intraoperative, and postoperative data were recorded. Postoperative follow-up was conducted at 2 and 4 weeks, and 6, 12, and 24 months. The primary and secondary outcomes and QoL were measured.

RESULTS

The female ratio was higher in both groups (P = 0.512). There was no significant difference between age and body mass index between the groups (P = 0.705 and P = 0.803). The mean defect size and mesh size were similar between the groups (P = 0.775 and P = 0.245). The mean operation duration and amount of blood loss were similar between the groups (P = 0.801 and P = 0.142). There was no statistically significant difference in the median visual analog scale scores between the groups (P = 0.551). During follow-up, only 3 patients (6.3%) in the ACST group and 4 patients (7.0%) in the non-CST group had recurrence. There was no significant difference in the short- and long-term QoL between the groups.

CONCLUSION

The ACST is a feasible surgical option for patients with complicated VHRs. In addition, by improving QoL, the recurrence rate is similar to patients undergoing standard VHR.
